Lithospheric dynamics and geochemical cycles on Earth through time
Date/Time: Wednesday, September 22, 2021 - 06:30 to 07:30
Venue: Online via zoom
Speaker: Dr. Vinod Oommen Samuel, Postdoctoral Researcher, Yonsei University, South Korea
Earth is a dynamic planet, continuously undergoing geochemical cycling due to its internal and external thermal processes. Geochemical signatures of the interactions of Earth’s surface and its solid interior are imprinted on various rock types exposed in the planet’s solid outer layer, called...

Understanding Earth’s lithosphere dynamics 2 billion years ago
Date/Time: Friday, September 3, 2021 - 03:00 to 04:00
Venue: Online via zoom
Speaker: Dr. Priyadarshi Chowdhury, Monash University, Australia

Continents, plate tectonics and life make our Earth unique in the solar system and perhaps, in the entire universe (at least, so far). However, none of them was...

Investigation of Interstellar Polycyclic Aromatic Hydrocarbon (PAH) molecules as carriers for mid-infrared emission bands
Date/Time: Monday, August 30, 2021 - 03:00
Venue: Online on Zoom
Speaker: Dr. Mridusmita Buragohain, Department of Astronomy, The University of Tokyo

Interstellar Polycyclic Aromatic Hydrocarbon (PAH) molecules exist in diverse forms depending on the local physical environment of the Interstellar Medium (ISM). Formation of ionized PAHs is favorable in the extreme condition of the ISM. Besides its pure form, PAHs are likely to exist in...
